Hi I need help figuring out what I can do. Im terrible with spells and magic but my power has something to do with strings like earlier this week my neck hurt like crazy but theni imagined a green string come from my hand and wrapping around my body and it made me feel so much better. Also when I first discovered this my friend was having a sad month and I wanted to help her so I imagined giving her a string that led her to happiness. Then the day after she was happy and good things started happening. But one day I took that string away from her hoping she can find her own way and then bad thing started to happen to her again what is this power and how do I use it
Its seems to me that you've created what is known as a "trigger." A trigger is a specific activity that can be used to direct your energy and create a specific outcome. So, by you imagining a string, you are subconsciously directing your energy and your intent (which is what a spell does) to heal yourself as well as leading your friend to happiness. This is not a "power" or "extra special ability." It's just a subconscious (and sometimes conscious) connection to your magical abilities. It's kind of like a short-cut in magick, to put it simply.
If it's not a trigger, then you are just doing a marvelous job with visualization. If you can visualize the outcome, then you can sometimes manifest it too, as visualization can also direct your energy and intent.
At any rate, continue to use this method. It sounds like it's very successful at accomplishing what you desire. :)
